turn home water heater up to ensure
water entering dishwasher is 120“F
(49°C) minimum. See recommended
procedure on page 14.
Use of incorrect
detergents
Use recommended dishwasher deter­
gents only.
Incorrect amount of
detergent
Follow recommendations on page 11 for
amount. Heavy soil and/or hard water
generally require extra detergent.
Use of ineffective
detergents
Detergent should be fresh. Store in a
cool, dry place, preferably in an airtight
container. Discard lumpy detergent.
Insufficient fill caused
by low water pressure
Home water pressure should be 20 to 120
psi for proper dishwasher fill. A booster
pump on the water supply may be neces­
sary if pressure is too low.

mended procedure on page 14.
Dishes Do Not Dry
Completely Dishes do not drain
properly Dishes must have proper water drainage.
Do not overload. Follow instructions for
loading dishwasher on pages 16-19. Use
a liquid rinse agent to speed draining.
Plastics Some plastics, due to material, may
need to be towel dried.
Silica Film or
Etching (Silica Film
is a White Irides­
cent Deposit;
Etching is a Cloudy
Film)
A water chemical
reaction with certain
types of glassware.
Usually caused by
some combination of
soft or softened water,
alkaline washing
solutions, insufficient
rinsing, over-loading
the dishwasher, and
heat of drying.
It may not be possible to prevent problem,
except by hand-washing. To retard this
process, use a minimum amount of
detergent but not less than one table­
spoon per load. Use a liquid rinse agent
and underload the dishwasher to allow
thorough rinsing. Silica film and etching
are permanent and can not be removed.
Use the Air Dry option.
Black or Gray
Marks on Dishes Aluminum items Aluminum items should be loaded so that
they will not rub against dishes during
washing. Throw-away aluminum items
should not be washed in the dishwasher
because they may break down and cause
marking. Aluminum markings can be
removed by using a mild abrasive
cleanser.
